Address Switches—
Set the address of the Remote Aux Panel (0 through 31) using
the switches marked PANEL ADDRESS on the right rear of the panel (see
Figure 2-33 ). The seven switches have 128 possible combinations; however, only
five of the switches may be used (1-16). Switches 32 and 64 must be in the OFF
position. If there is more than one panel, it may be useful to maintain a record of
each Remote Aux panel address.
CAUTION
Each panel must have a unique address. Setting the same address for two or more
panels will cause the entire Remote Aux system to malfunction.
Chop Enable Switch—
the following Chop Enable modes can be set on the 3-RU
panel:
■
Chop Enable Switch On– Allows Chop mode to be activated using the front
panel buttons
■
Chop Enable Switch Off– Disables Chop mode
Bus to be Controlled (Bus Enable) Switches— The 1-RU and 2-RU panels have
eighteen switches labeled BUS TO BE CONTROLLED. These set which aux bus is
controlled by the panel. Only one of these switches may be ON.
The 3-RU panel has eighteen switches labeled BUS ENABLE. These set which aux
buses can be controlled by the panel. Turn the switch ON for each aux bus to be
controlled. Any combination of the eighteen switches can be turned ON. The
functioning of the buses that have the switches turned OFF depends on the
position of the DEL LOGIC switch (see below).
If your switcher has only fourteen aux buses, the last four switches (8A through 9B)
must be set to OFF.
NOTE: Two or more panels can control the same aux bus; however, if the same bus is
selected on more than one panel and selections are made on both panels at the same time,
the panel with the highest address will control the bus.
